Ted,
Try 'counting to ten' before powering down.
If you move the VFO just before powering down, the VFO frequency may not
have been written to EEPROM yet, the process is not immediate.

I just finished debugging a K2 I built this past Spring and, with guidance
from Gus, KB0YH, it was in shape just in time to try it out in the FD. FB
so far. Except for one annoying problem.
When the rig is powered down it is supposed to remember the last frequency
it was on. The EPROM, I believe, is supposed to be continuously updated as
the VFO is moved. Well, this one doesn't do that. When the rig is shut
down and powered up it opens to the right band, and mode, and filter
selection; but the frequency isn't the last one used. It's sort of random -
sometimes a frequency used two or three repoweringups ago; sometimes a spot,
although in the band, that I don't even recognize. (Or maybe it's I who
can't remember where he was recently . . .?)
I haven't explored all of the other supposedly nonvolatile settings, like
the filter shaping, monitor settings, linearization and other parameters. I
have built and operated a handful of K2s over the years, and have never seen
this behavior, or not that I ever noticed. I thought I'd ask here if anyone
has seen this sort of thing, or if there are some particular investigations
I can make that would be of diagnostic value.
Thanks for whatever counsel might be offered . . .
Ted, KN1CBR
